WASHINGTON (AP) — The Internal Revenue Service has named a new official to help oversee the workers who process applications from groups seeking tax-exempt status.

Until now that post has been held by Holly Paz. Her name has surfaced in the investigations into IRS mistreatment of conservative groups seeking a tax-exempt designation.

An internal IRS announcement said Friday that Karen Schiller will have that job.

According to House Oversight and Government Reform Committee Chairman Darrell Issa, a California Republican, Paz was involved in an internal IRS investigation that in May 2012 essentially concluded that the agency had been targeting conservative groups.

That was a year before the IRS revealed the targeting publicly.

The announcement did not address Paz’s status. Some other IRS workers involved have been put on administrative leave.
